A 2.85W CW output, front-facet-emitted power and 54% maximum CW power
conversion efficiency have been obtained from aluminum-free, InGaAs/In
GaAsP/InGaP optimised-facet-coated, wide-stripe (100 mu m) diode laser
s emitting at 950nm. Half-wave ZnSe layers, deposited on the laser fac
ets prior to applying low/high reflectivity (LR/HR) dielectric coating
s, increase the maximum CW optical power by 50%. The power conversion
efficiency decreases by only 25% of its maximum value as the CW power
increases from 0.75 to 2.85W.
